Country A is rich in natural resources. These resources are evenly distributed across the country. Country B has resources concentrated at few places. The government of Country B is hindering the resource distribution due to vested interests. What could be a possible impact of this scenario?

Ihaven't done that yet, so no idea,but this is not the right place to ask

By water evaporation from the leaves is created a negative pressure at the top of the tree that promotes the ascension  of the water through channels that are called xylem. there are also two molecule forces that are involved: the intra-water molecules cohesion (water molecules stick to each other) and the adhesion when the water molecules stick to the channels they are running in. this is what enables water to go from the roots to the top of a tall tree.
